Personalized Information Before and After Total Knee Arthroplasty: PAK-study (PAK)

April 26, 2022 updated by: Kliniek ViaSana

Personal Feedback on Patient-reported Outcomes to Fulfil or Exceed Preoperative Expectations of Primary Total Knee Arthroplasty Patients: PAK-study.

Despite positive results following total knee arthroplasty (TKA), some patients are dissatisfied after recovery. Unfulfilled expectations is a key predictor of dissatisfaction. The aim of this study is to investigate if more patients fulfil or exceed their preoperative expectations one year after TKA when personal feedback on their PROs is given.
